Non-existing xpath does not throw exception for LazyDynaBeans
-------------------------------------------------------------
Key: JXPATH-144
URL: https://issues.apache.org/jira/browse/JXPATH-144
Project: Commons JXPath
Issue Type: Bug
Affects Versions: 1.3
Reporter: Mikael Nordenberg
The following code-snippet prints "null" when it should throw an exception:
LazyDynaBean bean = new LazyDynaBean();
JXPathContext context = JXPathContext.newContext(bean);
System.out.println(context.getValue("nonExisting"));
The problem is that in DynaBeanPropertyPointer:
protected boolean isActualProperty() {
DynaClass dynaClass = dynaBean.getDynaClass();
return dynaClass.getDynaProperty(getPropertyName()) != null;
}
Returns true, even if the property does not exist in LazyDynaBeans.
The issue is resolved if the implementation is changed to:
protected boolean isActualProperty() {
DynaClass dynaClass = dynaBean.getDynaClass();
if(dynaClass instanceof LazyDynaClass) {
return
((LazyDynaClass)dynaClass).isDynaProperty(getPropertyName());
} else {
return dynaClass.getDynaProperty(getPropertyName()) != null;
}
}
